What Do Healthy Ecosystems Sound Like?

Learn how sound recordings help scientists monitor environmental changes in this video from NOVA: What Do Healthy Ecosystems Sound Like? Much like an artist’s landscape visually captures a single moment in time, a soundscape captures noises in an environment coming from geophysical, biological, and human sources. Scientists called soundscape ecologists study these noise signatures. They use the noises to identify what is present in the environment at the time a recording is made and compare it with subsequent recordings to understand the changes occurring over time—specifically, how well different wildlife species are doing.
